In the present study, a novel catalyst was well designed by incorporating the tungstophosphoric acid into the magnetic chitosan, as highly stable composite, in which the iron oxides were used the strong super-magnetic core. The prepared composite was characterized by several methods, including FTIR, XRD, SEM, TEM and EDS and its catalytic activity was examined […]
In this work, chitosan biopolymer was cross-linked by starch oxide through the covalent bond formation between amine groups of chitosan and aldehyde functional of oxidized starch. A magnetic bio-support was obtained due to the treatment of the produced hybrid biopolymer with iron oxide nanoparticles. As a result of exposing of silver nitrate salt to magnetic […]
